There are 117 known elements (up to 118 excluding 117 which has not been created as of yet). 17 are non-metals: H, He, C, N, O, F, Ne, P, S, Cl, Ar, Se, Br, Kr, I, Xe, and Rn 9 are metalloids: B, Si, Ge, As, Sb, Te, Po, At, Uuo* The remaining 91 are metals. *Ununoctium, Uuo, is predicted to be a metalloid but there is no experimental verification of this.

Is a metal an element?
Metals are a class of elements. A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made of two elements, the metal tin and the metal copper.
What element is a nonmetal and a green gas?
Examples of non-metal elements that are gases include hydrogen, oxygen, and many others, while bromine is the only liquid non-metal element.
What other elements are in the Transition Metal family?
nickel, silver, gold, and cooper
What type of evidence would be expected to have trace elements?
glass and metal objects
What is a non-metal elements?
Hydrogen is one. There are many others, including nitrogen, oxygen, sulfur, phosphorus, argon, and chlorine.Nonmetal element is one of the elements which do not exhibit metallic properties, generally located in the upper right hand corner of the Periodic Table.A nonmetal is a substance that conducts heat and electricity poorly, is brittle or waxy or gaseous, and cannot be hammered into sheets or drawn into wire. Nonmetals gain electrons easily to form anions . About 20% of the known chemical elements are nonmetals.Examples of nonmetals are: nitrogenoxygenheliumsulfurchlorineFor more details refer to link below.
How many of the elements in an alloy must be metal?
At least one.
Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
What types of elements are found in an ionic compound?
metal and non-metal elements.
Silver white metal on the table of elements?
Many metals have a silvery appearance.
What are metal made out of?
Elements from the periodic table. There are many different types of metals.
All elements in the ALKALI-METAL family have how many valence electrons?
One
What elements form ionic compound?
metal and non metal elements
Are non metal elements never used in computers?
Are Non-metal elements used in computers
Is a metal that contains other elements to give it specific properties?
A metal that contains other elements to give it specific properties is called an Alloy. Many metals can contain other elements to give the metal specific properties. Steel is an alloy of Iron and carbon. Stainless steels contain various other alloying elements such as Chromium and Nickel.
How many elements are in a molecule of calcium carbonate (CaCO3)?
Three elements; the metal calcium in the positive portion of the compound, and the elements carbon and oxygen in the negative carbonate radical.
Is a metal?
"Metallic" is not a metal. But elements that are metals, are metallic.
Are most elements metals or pure?
Any metal that is not an alloy of a metal with other elements (metals, metalloids, or nonmetals) is a pure element. All of the metals listed on the Periodic Table are pure elements.
